"If you spill candle wax on a carpet, you can get it out by running an iron over it with a damp towel in between. I was so baffled I almost felt like spilling more wax.
Low heat, make sure the towel is damp enough, keep the iron constantly moving, and most importantly, don’t blame me if you light your carpet on fire."
